Linking the multiplier and the accelerator creates problems to most IB economics candidates even though in our watered-down version of things it is pretty simple.
I have prepared and uploaded a few extra notes (beyond what you find in our guide) that may prove useful here.
A very long time ago there has been an essay that focused on exactly this issue:
'Explain how the multiplier and the accelerator might be linked to each other'.
You know when? Back in May 1993 (my 1st IB candidates faced it). Were you guys born?
